nbdkit-example4-plugin is an example nbdkit(1) plugin written in Perl.
size=N parameter is required. It specifies the disk size in bytes. A single disk image, initially all zeroes, is created and can be read and written by all clients. When nbdkit shuts down the disk image is thrown away.
Mainly this is useful for testing and as an example of nbdkit plugins written in Perl. You should also read nbdkit-plugin(3) and nbdkit-perl-plugin(3). Note that nbdkit plugins may be written in C or other scripting languages.
nbdkit-example4-plugin first appeared in nbdkit 1.2.
